Title: Gas turbine engine compressor assembly
Inventor: HATFIELD JOHN EDMOND
IPC: F04D29/46
Filed: 1989-07-21
Abstract: A compressor assembly (12,13) for a gas turbine engine (10) comprises a centrifugal compressor (12) having a variable cross-sectional area diffuser (13) located at its downstream end. When the cross-sectional area of the diffuser (13) is less than a maximum value, some of the air exhausted from the downstream end (24) of the compressor (12) is directed to the upstream end (23) thereof. Sufficient air is so directed as to ensure that the mean air velocity at the outlet (30) of the diffuser (13) remains substantially constant.

Title: Apparatus and methods for controlling a signal device
Inventor: PEARLMAN BARRY S
IPC: B60Q1/26
Filed: 1989-09-05
Abstract: The device may produce an acoustic or radio signal, or particularly is a flashing light 51, 53 on a stationary warning sign or on an emergency vehicle. The lights may be flashed to give a repeating pattern including at least two different ON pulse widths and at least two different OFF space widths (Figs 3, 6, 8). Mode selection switches 29, 31, 33, 35 may be provided to select between a steady burn mode and different flash patterns (Figs 3 to 6). Alternatively, (Figs 7, 8) the selected modes may include flashing front lamps while rear lamps burn steadily, or vice versa, or steady burning of front and rear lamps. Different patterns may be concurrently produced at outputs A, B respectively energising lamps 53, 51. Outputs A, B may also be connected to acoustic warning devices. The flash patterns may be stored in a memory (121), (Fig 2), the stored values being addressed in sequence by a counter (93). The memory (121) may have an output (Q4), (Fig 8), which causes the frequency of an oscillator in the counter (93) to be changed at least once in each cycle of the pattern currently in use. <IMAGE>

Title: Methods and apparatus for use in pipe lining.
Inventor: BIRCH MALCOLM WILLIAM
IPC: F16L55/165
Filed: 1989-09-12
Abstract: A pipe (11) e.g. a water main is lined by moving a thermoplastic liner (10) without heat through a die (16) to reduce the cross-section of the liner, and introducing the reduced liner (10) into the pipe (11). The liner (10) subsequently moves into engagement with the inner surface of the pipe (11) by recovery in cross-section on release of axial tension. A flexible expansion device Fig. 8 may be moved through the liner to expand the liner into engagement with the pipe. The die (16) may be mounted on the pipe (11) and be in separable parts. The minimum cross-section of the die (16) may be on a part replaceable by another part defining a different cross-section. The liner material may be polyolefin, polyamide, polyvinyl chloride, ABS. <IMAGE>

Title: Fatigue monitoring
Inventor: PRESCOTT NICHOLAS JOHN
IPC: G01N3/32
Filed: 1989-10-13
Abstract: A method for monitoring structure liable to fatigue by sustained loading, which may be repeated or cyclic, under which crack-like flaws may grow and lead to fatigue or fatigue-induced failure, comprises providing in a gauge which may be integral with or secured to the structure an initial flaw in a position from which a crack will grow, under the loading, in a predetermined manner depending upon the loading, and monitoring growth of the crack to determine the condition of the structure. Apparatus for the same includes a tab-like gauge 201 or other appendage which has a flaw, preferably made by a fatiguing process, and means for prestressing the gauge so that it will correctly respond to the in service static load. An example given in a gauge for a wing spar which when the plane is grounded is under opposite static loading to when it is in the air in service. Gauge 201 has an initiated crack 202 and is attached to blocks 203 glued to the structure by pins 204. Prior to attachment, blocks 203 are urged apart to apply a predetermined stress by wedge elements 205. Means may be provided for adjusting the prestress. Alternatively prestressing may be provided by the stress-inducing or stress relieving techniques applied to the gauge body as by local heating. Various gauges are shown, which may be glued welded, bolted or pinned to the structure or to an intermediate plate attached to the structure. Resistance, magnetic or acoustic properties of a gauge may be monitored. Alternatively visual inspection of crack growth may be enhanced by a scale or coloured markings. Optical fibres across the crack growth path may monitor growth. <IMAGE>

Patent GB-2245740-A (GB)
Title: Character encoding
Inventor: WRIGHT PHILIP TIMOTHY
IPC: G06V30/10
Filed: 1990-07-03
Abstract: A hand-written character to be encoded is defined by digital data, typically from a graphics tablet, comprising successive x, y co-ordinate positions. The digital data is encoded (e.g. using x, y encoding) into a series of arbitrary line vectors LV1, LV2, etc and the arbitrary line vectors are subsequently encoded (e.g. using Freeman encoding) into a series of pre-defined line vectors FV1, FV2 etc to afford a character encoded signal. Corresponding ones of the arbitrary line vectors LV1, LV2, etc are compared with the pre-defined line vectors FV1, FV2 etc in order to derive one or more alternative character encoded signals which improve the chances of the character being recognised.

Title: Pellet implantor with lost motion means to prevent crushing
Inventor: PHILLIPS IAN ROSS
IPC: A61M36/12
Filed: 1991-02-18
Abstract: An implantor 10 to inject a pellet containing a medication, into an animal via a hollow needle 15 comprises a push rod 42 which moves a pellet through the needle 15 so that the pellet can be delivered into a subcutaneous cavity formed by the needle 15. Associated with the push rod 42 is a spring 43 providing a lost motion mechanism so that the push rod 42 does not apply to the pellet an excessive force which would cause crushing of the pellet. The push rod 42 is moved by means of a trigger mechanism including a trigger 29 operated by the user to cause rotation of a reel 34. Wound about the reel is an elongated flexible strip 35 which is attached to the push rod 42. Operation of the trigger 29 causes the reel 34 to rotate, winding about it the metal strip 35. The implantor 10 is provided with a magazine 13 having a series of pellet containing cavities 21 which are successively aligned with the needle 15 and push rod 42. An indexing mechanism 47 associated with the push rod 42 causes indexing of the magazine 13 to align the next pellet to be injected with the needle 15. <IMAGE>

Title: Hydraulic lift control
Inventor: HATANO KAZUHIRO
IPC: B66B1/26
Filed: 1991-03-07
Abstract: A hydraulic elevator is actuated by means of valve 9 controlling the amount of oil in jack 3. Oil temperature sensor 17 and oil pressure sensor 16 allow corrections to be made to the valve opening profile so as to compensate for variations in oil viscosity (due to temperature) and lift load. The sensor outputs are assigned to 'low', 'medium' or 'high' categories, or a mixture thereof, by means of fuzzy logic; the corrections due to each category are summed with appropriate weights to obtain a total correction. Further corrections can be introduced by comparing the actual lift acceleration, speed and deceleration with desired values; only the medium temperature, medium pressure correction is updated (Fig 11). <IMAGE>

Title: Descrambling system for broadcast television signals scrambled by active line rotation
Inventor: ROBINSON ADRIAN PAUL
IPC: H04N7/169
Filed: 1992-02-14
Abstract: A descrambler for descrambling a signal scrambled by active line rotation (i.e. by interchanging two portions of a line, Fig 1) has a pair of line stores 8 connected to a descrambling control input 13 (receiving data on the cut point between the two portions) to effect the line rotation. A tilt measurement circuit 3 measures line tilt, namely any overall change in video amplitude level across a line, and compensates by generating 4 a converse ramp signal which is added 5 to the video signal. The ramp signal is generated to ten-bit accuracy whereas the video signal has only eight bits. The two least significant bits are accumulated 6, 7 on a sample-by-sample basis to effect error feedback. Thus the visibility of image artefacts due to contouring is reduced. <IMAGE>
